介绍如何在StrongArm下编写shellcode的知识。一开始先介绍了StrongArm的体系结构和指令集，后面给出了几个shellcode的实例。这些实例在HP iPAQ上的Debian Linux上开发，但原理可通用于StrongArm下的其他机型和其他linux版本。(This guide describes how to write shellcode in StrongArm architecture. At first it introduced the StrongArm architecture and instruction set, then it given a few examples of shellcode. The examples developed on HP iPAQ running Debian Linux, but the principle may be applicable to other models and other linux deployment.)
